      I think within the geological period known as “Mesozoic”, 250 to 65 million years ago.

      So dinosaurs died a long time ago!we can age dinosaurs by looking a the growth rings inside their fossilized bones. So some smaller dinosaurs present in seawater might have lived for 300 years, other medium sized dinosaurs lived for 50-80 years, while a T-Rex may have only lived for 30 years
